Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of pinch roll polishing, and particularly relates to an online polishing device for a coiling pinch roll. BACKGROUND

[0002] In the production process of hot-rolled strip steel, the pinch roll is one of the key auxiliary equipment, and its main function is to realize the tracking and stabilization of the strip steel through the control of the pinch roll in the coiling process of the strip steel. However, the surface of the pinch roll is prone to sticking to the steel during long-term use, which will cause surface quality defects of the strip steel and affect the quality of the final product. In order to solve this problem, the traditional method is to use manual polishing to clean and maintain the surface of the pinch roll.

[0003] The existing polishing technology for the surface of the pinch roll mainly relies on manual operation, and the workers use polishing stones to polish the surface of the pinch roll in the stopped state. Although this polishing method can temporarily solve the sticking problem, it has the following defects: manual polishing requires a lot of physical effort, and the operating environment is high in temperature and harsh, which affects the health and safety of the operators. Due to the limitation of manual operation, it is difficult to ensure uniformity and consistency during the polishing process, which may cause uneven polishing and affect the surface quality of the strip steel. Each polishing needs to be stopped, which increases the downtime of the production line, reduces the production efficiency, and increases the production cost.

[0004] Therefore, we propose an online polishing device for a coiling pinch roll, which realizes the online polishing function through automatic control and intelligent design, effectively improves the polishing efficiency and quality, reduces the downtime, labor intensity and maintenance cost, and improves the production safety and economic benefits. SUMMARY

[0005] The technical problem to be solved by the present application is that the existing polishing method relies on manual holding of polishing stones and is stopped for polishing, which has the problems of high labor intensity, high safety risk, uneven polishing, long time consumption, and serious influence on production efficiency and product quality.

[0006] The utility model discloses a kind of online polishing devices for coiling pinch roll, the device can automatically polish pinch roll, improve polishing quality and efficiency, reduce labor intensity and safety risk, while not affect the normal operation of production line.

[0007] To achieve the above object, the utility model provides the following technical scheme:

[0008] The application relates to a coiling pinch roll on-line polishing device, which comprises a polishing mechanism, a driving mechanism and a mounting bracket, the polishing mechanism comprises upper pinch roll polishing devices and lower pinch roll polishing devices, the driving mechanism is used for driving a grinding head to move along the axial direction and the radial direction of a pinch roll, the mounting bracket is fixed on the rack of a coiling machine and is used for mounting the polishing mechanism and the driving mechanism, so that the polishing mechanism and the driving mechanism can cooperate to polish the pinch roll on line.

[0009] The upper pinch roll polishing device and the lower pinch roll polishing device each comprise a grinding head and a grinding stone fixed on the grinding head;

[0010] The driving mechanism comprises a cylinder clamping positioning mechanism and a cylinder sliding table mechanism, the cylinder clamping positioning mechanism drives the grinding head to feed, and the cylinder sliding table mechanism is used for driving the grinding head to swing;

[0011] As a preference, the mounting bracket comprises a fixing frame fixed on the rack of the coiling machine, a guide shaft fixed on the fixing frame, a guide frame sliding along the guide shaft, a fixing shaft fixed on the guide frame and a shaft sleeve sleeved on the outer side surface of the fixing shaft.

[0012] As a preference, the cylinder clamping positioning mechanism comprises two connecting blocks symmetrically mounted on the guide frame and a clamping cylinder, the fixed end of the clamping cylinder is rotationally arranged on the connecting block, the piston rod end is rotationally connected with a connecting rod on the shaft sleeve, and the end, away from the clamping cylinder, of the connecting rod is fixedly connected with the grinding head. The clamping cylinder drives the connecting rod and the shaft sleeve to rotate, drives the grinding head and the grinding stone at the end of the connecting rod to abut against or move away from the surface of the pinch roll, so as to clamp or loosen the pinch roll.

[0013] As a preference, the cylinder sliding table mechanism comprises a double-shaft double-rod sliding table cylinder, the double-shaft double-rod sliding table cylinder is fixed on the fixing frame, and the shaft rods at the two ends of the double-shaft double-rod sliding table cylinder are fixedly connected with the guide frame.

[0014] The double-shaft double-rod sliding table cylinder drives the guide frame and the cylinder clamping positioning mechanism on the guide frame to swing left and right, and the polishing effect of the left and right swinging is better.

[0015] As a preference, the grinding stone is a diamond grinding stone.

[0016] Compared with the prior art, the technical effects and advantages of the application are as follows:

[0017] The design of the driving mechanism of the coiling pinch roll on-line polishing device enables the grinding head to move along the axial direction and the radial direction of the pinch roll and to swing left and right, thereby improving the polishing quality and efficiency. Compared with the existing manual polishing, the automatic polishing mode greatly improves the consistency and uniformity of polishing.

[0018] The automation feature of the online polishing device reduces the labor intensity of manual operation, and the automatic pressing and loosening mechanism ensures stable contact between the grinding head and the pinch roller, thereby ensuring the continuity and consistency of the polishing effect. The left and right swing function of the cylinder sliding table mechanism shortens the polishing period and reduces the downtime of the production line, thereby significantly improving the overall production efficiency. By realizing online automatic polishing of the pinch roller, the device eliminates the safety hazards in the manual polishing process, reduces the labor intensity of workers, and improves the working environment. The automatic polishing process reduces the need for workers to directly contact the grinding stone and the high-temperature pinch roller, improving work safety.

[0019] The diamond grinding stone has extremely high hardness and wear resistance, and can efficiently complete the polishing task of hard materials. The service life of the diamond grinding stone is longer, reducing the frequency of replacing the grinding stone, thereby reducing the maintenance frequency and cost. At the same time, the entire polishing process does not require manual intervention, reducing equipment failures and maintenance costs caused by improper human operation.

[0020] The design of the mounting bracket ensures the stability of the polishing mechanism and the driving mechanism, reduces vibration and displacement, and ensures the stability of the polishing process. The symmetrical installation of the connecting block and the clamping cylinder on both sides balances the pressure, avoids damage to the pinch roller caused by uneven pressure, and improves the positioning accuracy and polishing efficiency.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts under the premise that no creative efforts are made, belong to the scope of protection of the present application.

[0027] The technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Figures 1 to 4 The present application is further described in detail,

[0028] The embodiment of the present application discloses a coiling pinch roll on-line polishing device, which comprises a polishing mechanism, a driving mechanism and a mounting bracket, the polishing mechanism comprises an upper pinch roll polishing device and a lower pinch roll polishing device; the driving mechanism is used for driving the grinding head 1 to move along the axial and radial directions of the pinch roll 4, the mounting bracket is fixed on the rack 3 of the coiling machine, and is used for mounting the polishing mechanism and the driving mechanism, so that the polishing mechanism and the driving mechanism can cooperate to polish the pinch roll 4 on line.

[0029] The mounting bracket comprises a fixing frame 5 fixed on the rack 3 of the coiling machine, a guide shaft 6 fixed on the fixing frame 5, a guide frame 7 sliding along the guide shaft 6, a fixing shaft 8 fixed on the guide frame 7, and a shaft sleeve 9 rotatably sleeved on the outer side surface of the fixing shaft 8. The design of the mounting bracket enables the polishing mechanism and the driving mechanism to be stably mounted on the rack 3 of the coiling machine, reduces vibration and displacement, and ensures the stability of the polishing process.

[0030] The upper pinch roll polishing device and the lower pinch roll polishing device both comprise a grinding head 1 and a grinding stone 2 fixed on the grinding head 1; the grinding stone 2 is a diamond grinding stone 2. The diamond grinding stone 2 has extremely high hardness and wear resistance, can efficiently polish hard materials, reduces the frequency of replacing the grinding stone 2, and improves the polishing efficiency and polishing quality. Meanwhile, the service life of the diamond grinding stone 2 is relatively long, and the maintenance cost is reduced.

[0031] The driving mechanism comprises a cylinder clamping positioning mechanism and a cylinder sliding table mechanism, the cylinder clamping positioning mechanism drives the grinding head 1 to feed, and the cylinder sliding table mechanism is used for driving the grinding head 1 to swing;

[0032] The cylinder clamping positioning mechanism comprises two connecting blocks 10 symmetrically installed on the guide frame 7 and a clamping cylinder 11, the fixed end of the clamping cylinder 11 is rotatably arranged on the connecting block 10, the piston rod end is rotatably connected with a connecting rod 12 on the shaft sleeve 9, and the end, away from the clamping cylinder 11, of the connecting rod 12 is fixedly connected with the grinding head 1.

[0033] The clamping cylinder 11 drives the connecting rod 12 and the shaft sleeve 9 to rotate, drives the grinding head 1 and the grinding stone 2 at the end of the connecting rod 12 to be attached to the surface of the pinch roll 4 or to be away from the surface of the pinch roll 4, so as to clamp or loosen the pinch roll 4.

[0034] The connection block 10 and the clamping cylinder 11 symmetrically installed on both sides can balance the pressure and avoid damage to the pinch roll 4 caused by uneven pressure, while improving the accuracy of positioning and the efficiency of polishing.

[0035] The cylinder sliding table mechanism includes a double-shaft double-rod sliding table cylinder 13 fixed on the fixed frame 5, and the shaft rods at both ends of the double-shaft double-rod sliding table cylinder 13 are fixedly connected with the guide frame 7.

[0036] The double-shaft double-rod sliding table cylinder 13 drives the guide frame 7 and the cylinder clamping and positioning mechanism on the guide frame 7 to move left and right, and the left and right movement is better for polishing the pinch roll 4.

[0037] The fixed connection of the double-shaft double-rod sliding table cylinder 13 and the guide frame 7 improves the rigidity and stability of the mechanism, so that the grinding head 1 moves more stably when it swings, avoiding uneven polishing or surface damage caused by vibration.

[0038] The cylinder clamping and positioning mechanism makes the grinding head 1 move axially along the pinch roll 4, and the grinding stone 2 on the grinding head 1 presses or releases the pinch roll 4.

The swing function enables the grinding head 1 to cover more surface of the pinch roll 4, achieving all-around polishing and improving the polishing quality and efficiency.

[0039] The coiling pinch roll online polishing device realizes the online polishing of the surface of the pinch roll 4 through the coordinated work of the carefully designed polishing mechanism, driving mechanism and mounting bracket. The polishing mechanism includes two polishing devices, the upper pinch roll and the lower pinch roll, each of which is equipped with a diamond grinding stone 2. These grinding stones 2 can efficiently complete the polishing task of hard materials due to their extremely high hardness and wear resistance. The driving mechanism consists of a cylinder clamping and positioning mechanism and a cylinder sliding table mechanism. The former is responsible for the axial feeding and pressing and releasing of the grinding head 1, and the latter is responsible for the radial swing of the grinding head 1. The mounting bracket ensures that the entire device is stably installed on the coiler rack 3, reducing vibration and displacement, thereby ensuring the stability and uniformity of the polishing process.

[0040] The automation features of the online polishing device significantly improve production efficiency. The automatic pressing and loosening mechanism reduces the labor intensity of manual operation, while ensuring stable contact between the grinding head 1 and the pinch roll 4, thereby ensuring the continuity and consistency of the polishing effect. In addition, the left and right swing function of the air cylinder sliding table mechanism enables the grinding head 1 to cover more surfaces of the pinch roll 4, achieving all-around polishing, which not only improves the polishing quality, but also shortens the polishing cycle, thereby reducing the downtime of the production line and improving the overall production efficiency.

[0041] The online polishing device reduces the labor intensity of workers, eliminates safety hazards in the manual polishing process, and improves the working environment. Due to the use of diamond grinding stones 2, the frequency of replacing the grinding stones 2 is reduced, and the service life is extended, which not only reduces the number of maintenance, but also reduces the maintenance cost. The entire polishing process does not require manual intervention, reducing equipment failures and maintenance costs caused by improper human operation, thereby achieving efficient, economical, and safe pinch roll 4 polishing operations.
